The bung of ware is supported ona disk secured to the upper end of a piston rod 36 extending upwardly from a cylinder 31 mounted upon an upright 38 extending between the lower and-intermediate cross members 22, .23, see. Figurei. -By means of this piston and cylinderarrangement, the bung support 35 is moved vertically toward and from the chutes 28, 29, and the support is arranged-coaxially therewith.

The reiractory material is compacted between the rims of the pieces. of ware of the bung by a pending therefrom, the lower end of, which is encircled by a second cylindrical chuteZil supported, 'asby screws 3B depending from a pair of cross members 3| mounted on the" channel elements 2| and extending diagonally across the corner portions thereof, as shown inFigures 2 and 3, the screws 30 being mounted in a ring member 33 fixed to the under side of the supports 3 I, the screws being'provi'ded with adjusting nuts ward and from the upper chute 28.

cylindrical casing 40, known as a coddle, carried by mechanism depending from a carriage 4| provided with a plurality of rollers 42 mounteclupon an annular track member 43 secured to the under sides of the channel elements 2|, see FiguresZ, 3 and 4. The rollers 42 are journalled on studs 45 mounted. in vertically extending flange members 46 welded or otherwise secured at points circumferentially spaced about the periphery of the carriage 4! which is formed with a large central aperture to permit free rotation of the carriage on the track 43 about the lower chute 29. A gear reduction motor 41 is mounted upon an angle member 48 secured to the channels 2| of the top-frame member adjacent one corner; thereof, see Figures 2 and 3. The output shaft from the gear reduction motor depends fromi the unitand has afiixed to its lower end a sprocket 50. A'ring 5|, formed of insulating material, is fixed to the carriage 4 I, as by screws 52, and is positioned to encircle the lower chute 29, the screws '52 also serving to attach a sprocket 54 to the member 5|, and a drive chain 55 is trained about the sprockets 50, 54. This provides power means for effecting rotation'of the carriage about the axis of a bung of ware positioned upon the support 35. p

The casing 40-is connected. at its" opposite side portions to and supported by motion transmitting or actuating members 56 pivotally mounted at their upper ends in bifurcatedbracket'st 51 secured to the under side of the carriage disk 4| as by pins 58, see-Figure 6. The lower end portions of the members 56 are formed with relatively wide slots, the opposing vertical walls of. which are provided with wear plates 60 to receive the outer race of an anti-friction bearing 6|, see Figure 7. This bearing is mounted onv a sleeve 52 having an eccentrically arranged bore to receive a shaft 63.

collar portion 64 formed with a radial slot 55 and a clamp-screw 66, Figure 9.- The end portion of the shaft 63, on which sleeve 62 is mounted, has its periphery eccentric to its axis. Accordingly the eccentricity of the sleeve 62 and bearing The sleeve 62 is formed with an enlarged.

parent from'Fig'ures Tand 9.

The shafts 63 are journalled intermediate their ends in bearings 68 mounted in housings 69 supported by channel members 70 depending from the under side of the carriage M. The ends of the shafts 63, on which the sleeves 62 are mounted, are fastened to shafts 12 of motors 13, as by pins 14. The motors 13 are, in turn, mounted upon a pair of channel members l depending from the under side of the carriage 4|. During rotation of the carriage 4i about its vertical axis, the motors 13 are supplied'with power from collector rings 16 mounted upon the insulating ring 51 and supplied with current by branches not shown. I V V The casing '40'is'provided' on opposiltesides circuit to the actuating motor for the conveyor 86 whereupon a quantity of the clay refractory material is deposited in the hopper 24 and descends about thebung of ware in the casing. As

the claymaterial is discharged between the bung and the casing '40, opposite'side portions of the casing are reciprocated by the eccentric mechanisms connected to the motors 13 and simultaneously, the carriage 4| is rotated about the axis with radially extendingfiange members ll, these 7 members being spaced apart tojreeeive the actuating members 56. The flanges-J1 have affi xed to theirjinnerconfronting faces, plates 78. These plates and the flanges -11 are formed with elongated'vertically 'extendingfslots'lfi to receive bolts 80. The-members 56 are apertured to receive a bearingbushing 8| in'which is mounted a spacing'sleeve82 ,and throughwhich the bolt an extends; and'which formsa spacer between the plates 78 so'that the bolt may be tightened by nut 63, Figure 7. r I I Withthis arrangement, the casing 40 is supported by the'membe'rs 56, and'the casing may be adjusted vertically so that the force exerted by theeccentric mechanism to effect reciprocation of opposite sides of the casing may be applied at diifer'ent'points vertically along the casing. The adjustment of the eccentricity ofthe members 62 provides for variation-in'the amplitude of the reciprocation of the casing;

The refractory clay material is fed to the hopper 24'by any suitablemeans asthe conveyor belt 86, Figure 4. This belt is trained over a pulley 81 journalled on the-conveyor frame 88 and is located within the'hopper 24. 'The pulley 81 is intermittently rotated'in the direction of the arrow 90 by amotor, not shown, whereby the clay refractory material, carried by the upper run of the belt 86, is deposited into the hopper '24 from whence it descends through the chutes 28, 29, and is directed in the annular spacebetween the bung of ware and-the casing 40 by a conical member 92 secured to a tubularmember 93 slidably moun'tedin a spider member 94 mounted in thelower end of the chute 28 and in a guide hearing 95 mounted in the transverse member 26. A member 96 formed of yieldable material, such as sponge rubber, is fixed'tothe base of the conical member92. 1

In operation, a bung'of ware is placed upon the support.-35, fluid pressure is applied to the lower end of the cylinder 3'1, causing the support to move upwardly and .position the bung within the casing '49. During. this upward movement, the topmost plate in the stack of the bung is engaged by the member "96 and the conical member 92 is moved'upwardly to the position shown in Figure 4. The upward movement of the support 35 is controlled by a stop in the nature of a chain 98, the ends of which are secured to the cylinder 3? and the support 35. At the end of the upward stroke of the support, a switch is actuated by a pin 95 secured to the support 35, the pin engaging a switch actuator I89. This switch closes a when the-bedding material has been supplied in sufiicient quantityto effect embedding of the bung, whereupon the power supply to the conveyor is=opened"manually, and the support 35 lowered to permit removal of the embedded bung. Upon downward movement of the support 35, the bung of ware is lowered from the casing 40, the conical member 92 and the resilient member following the bedded bung of were downwardly. The stem'93 is provided with stop collars HM to limitdownward movement of the? members 92; 96, when the same reach "a position at the bottom of the casing 40. The motors 41, 13 may beeperated continuously, or may be stopped and started for the bedding operation of each bung of ware. Preferably, the casing 40 is formed .'of' thin sheet resilient material, such as steel,iand the reciprocation is such that opposite side portions of the casing are simultaneously moved inwardly and outwardly. In order that the eccentric mechanisms may thus operate in synchronism, the sprockets I05 are aihxed to the outer ends of the shafts 63 and are connected by means of aroller chain I06. w
